This orphaned white rhino calf was gravely injured by poachers, but thanks to emergency surgery and the care of wildlife veterinarian Cobus Raath and his team, little Shangi is on the mend, getting mudbaths, and joyfully running about with her caregivers. From the Smithsonian Channel’s Baby Planet: Human Intervention: Running with Rhinos.

Bonus video: Baby rhinos sound adorable.

This is a male Sapphirina copepod or Sea Sapphire, transparent and only a few millimeters long, but attention-grabbing when they seem to emit an incredible blue flash. What causes luminous color from nothing? The “microscopic layers of crystal plates inside their cells” catch light and reflect back the violet-blue. Rebecca R. Helm writes:

Like their namesake gem, different species of sea sapphire shine in different hues, from bright gold to deep blue. Africa isn’t the only place they can be found. I’ve since seen them off the coasts of Rhode Island and California. When they’re abundant near the water’s surface the sea shimmers like diamonds falling from the sky.  Japanese fisherman of old had a name for this kind of water, “tama-mizu”, jeweled water…

In the case of blue sea sapphires, these crystal layers are separated by only about four ten thousandths of a millimeter; about the same distance as a wavelength of blue light. When blue light bounces off these crystal layers, it is perfectly preserved and reflected. But for other colors of light, these small differences in distance interfere, causing the colors to cancel out. So while white light is composed of all colors, only blue light is reflected back.

More iridescence: the Blue Morpho Butterfly, Peacock Spiders, and the Birds of Paradise.

This unusual underwater journey in South Africa involves kayaking legend, French expat, and mad inventor Olivier Feuillette, and a modified kayak. With a waterproof top, a ballast (so that it will sink), scuba tanks for oxygen, a CO2 filter, an oscillating fishtail, and pedals, Feuillette’s SUBO becomes a one-person submarine that’s ready to go where no kayak has gone before.

Spend three minutes underwater with the abundant marine life of South Africa's coral reefs. Patterned moray eels, banded coral shrimp, the orange rock cod, the spotted yellow boxfish, and more are featured in episode 15 of EarthTouchTV’s Wild Oceans.

We are constantly underwater in the archives, including this incredible, animal-packed footage of a sardine run and the tranquil Kuroshio Sea Aquarium in Okinawa.
